UK: Orkney Islands generates more renewable energy than it can use.

Orkney is a leader in renewable energy, using wind and tidal power to exceed its electricity needs. The community benefits from wind turbines, but faces challenges with energy overproduction. Excess energy is converted into hydrogen, reducing emissions. Orkney's success demonstrates a sustainable model for the UK, with potential for tidal energy to contribute significantly to the national grid.

What is one of the main challenges faced by the community-owned wind turbine on Shapen?

• Overloading of the power cable to the mainland

• Lack of wind to generate electricity

• Insufficient funding for operations

• High maintenance costs

How is the excess wind energy utilized on Shapen?

• It is stored in batteries for later use

• It is used to power electric vehicles

• It is converted into hydrogen energy

• It is sold to neighboring islands

What was the primary source of heating for the island school before switching to hydrogen?

• Natural gas

• Coal

• Solar panels

• Oil

What makes tidal energy a reliable source of power?

• The tides are highly predictable

• It requires minimal infrastructure

• It is available 24/7

• It is unaffected by weather conditions

What percentage of the UK's electricity could potentially be supplied by scaled-up tidal turbines like the Orbital O2?

• 5%

• 10%

• 15%

• 20%
